Newton's Law of Motion

Which law of motion states that,for every action, there is an equal and opposite reaction?

• Newton’s First Law of Motion

• Newton’s Second Law of Motion.

• Newton’s Third Law of Motion

• The law of reaction.

What is an example of how friction can be helpful?

• A skateboard ramp

• A seatbelt in a car.

• The brakes on a car

• The wheels on a bicycle.

If you kick a bowling ball and a tennis ball with the same amount of force,according to Newton’s Second Law of Motion,what will happen?

• The tennis ball will travel farther than the bowling ball

• The bowling ball will travel farther than the tennis ball

• The bowling ball will travel faster,but cover a shorter distance

• The balls will travel the same distance.

According to Newton’s First Law of Motion…

• An object in motion will slow down when moving down a hill

• An object in motion will stay in motion unless acted upon by an outside force.

• An object in motion will always move sideways when acted upon by an outside force.

• An object in motion will stay in motion when it is acted upon by an outside force.

The SI unit for for force is.

• Gram

• Centimeters

• Meters

• Newton

Newton's second law of motion describes the relationship among force, mass and acceleration. The correct equation is.

• F= m X a

• F= m / a

• a = m X F

Inertia is...

• An object's movement

• An object's resistance to a change in its motion

• An object's acceleration

• An objects velocity

If you increase the force on an object, its acceleration increases

• true

• false

If you increase the mass of an object, its acceleration decreases

• true

• false

The amount of inertia an object has depends on its speed

• true

• false
